Meta-learning-enhanced implicit full waveform inversion
Zefeng Wang, Shijun Cheng, Weijian Mao +2
Implicit full waveform inversion (IFWI) introduces implicit neural representations to parameterize the subsurface velocity model as a continuous function of spatial coordinates, wh…
Adaptive Self-Supervised Surface-Related Multiple Suppression
Huan Song, Shijun Cheng, Huanhuan Tang +2
Effective suppression of surface-related multiples is essential to prevent imaging artifacts and erroneous structural interpretations. While conventional approaches rely on accurat…
Inhomogeneous plane waves in attenuative anisotropic porous media
Lingli Gao, Weijian Mao, Qianru Xu +3
We investigate the propagation of inhomogeneous plane waves in poro-viscoelastic media, explicitly incorporating both velocity and attenuation anisotropy. Starting from classical B…
Generative Diffusion Model for Seismic Imaging Improvement of Sparsely Acquired Data and Uncertainty Quantification
Xingchen Shi, Shijun Cheng, Weijian Mao +1
Seismic imaging from sparsely acquired data faces challenges such as low image quality, discontinuities, and migration swing artifacts. Existing convolutional neural network (CNN)-…
Atomic decomposition of real-variable type for Bergman spaces in the unit ball of
Zeqian Chen, Wei Ouyang
In this paper, we show that every (weighted) Bergman space in the complex ball admits an atomic decomposition of real-variable type for any $0 < p…
